show port qos<br />
show qos status<br />
Catalyst 6500 PFC2/PFC3—<strong>QoS</strong> Considerations and <strong>Design</strong><br />
The Catalyst 6500 CatOS show port qos verification command returns the configured and runtime <strong>QoS</strong><br />
states of a port. These may differ, as certain commands need to be committed (programmed into<br />
hardware) before they become effective.<br />
In the example below, the switch has <strong>QoS</strong> globally enabled and the source of <strong>QoS</strong> policy decisions is the<br />
local configuration, as opposed to a Common-Open Policy Source Policy-Decision Point (COPS PDP).<br />
Furthermore, the output shows that the port is configured for port-based <strong>QoS</strong> (by default) and has been<br />
set to trust DSCP from connected endpoints. No trust-extension has been configured, as this is not a<br />
conditionally-trusted endpoint model.<br />
The output includes the linecard’s queuing capabilities: 1P3Q1T (Transmit) and 1P1Q0T (Receive), as<br />
well as any ACLs that may be mapped to the port (however, no ACLs have been mapped to this port in<br />
this particular example).<br />
